I find the A9 Home to be a very exciting development and am keen to see exactly what 2005 brings us. At the moment we don't have a capable mid/low range machine available to purchase. The Iyonix is priced for what it is - the fastest machine we have currently. So, unless an ARM 7500 meets your needs, your only option is to purchase a second-hand tricked out 10 year old machine.
Also the speed of the ARM 9 that will power the A9 Home has not been decided. As was pointed out in "Lifting the lid on the A9" and again in this thread - ARM9's can range as high as 533Mhz. While I don't imagine that we'd be lucky enough to see a 533Mhz A9 Home, I'd be even more surprised if the final spec of the production model was 200Mhz. If for no other reason than to avoid problems similar to those that RISCstation faced - marketing a new machine with a lesser/same clockspeed as machines currently in circulation.
And to finish I'd just like to say I'm looking forward to seeing the mystery of the drawfile acceleration revealed - go STD/A6 ! ^_^
